The Rotor Beater Mill SR 300 is suitable for coarse and fine size reduction, either in batches or continuously. It can process dry, soft, medium-hard, organic and inorganic substances.
Its high speed in comparison to the SR 200 allows a significantly higher throughput and fineness.
The SR 300 is intended for universal use: from sample preparation in laboratories up to preparing sample batches in pilot plants or production facilities. The grinding chamber, the feed hopper and the material inlet are completely made from high quality stainless steel.

Application Examples:

bentonite, chemical products, coal, coke, drugs, feed pellets, fertilizers, food, graphite, gypsum, herbs, pharmaceutical materials, plant materials, plastics, powder coating, resins, rice, salts, seeds, soils, spices, sugar, …

Product Advantages:

suitable for batchwise operation of larger quantities
high final fineness
exchangeable grinding and sieve inserts
grinding chamber, feed hopper and material inlet and outlet of stainless steel
optional grinding inserts 180° for grinding of hard-brittle materials by additional impact
